Countering Web Spam Using Link-Based Analysis

by James Caverlee, Mudhakar Srivatsa, Ling Liu
"... Web spam refers to efforts by malicious adversaries to manipulate how users view and interact with the World Wide Web, often to drive traffic to particular spammed Web pages, regardless of the merits of those pages. As the Web has grown and increasingly become the primary platform for information sh ..."

spam: • Page Spoofing: To support identify theft, Web spammers often construct illegitimate copies of legitimate Web sites (like www.ebay.com). Users are then directed to these spoofed sites through email-based phishing attacks or spammer-controlled fake Web directories. • Browser-Based Attacks

Using Content-based and Link-based Analysis in Building Vertical Search Engines

by Michael Chau, Hsinchun Chen - in Proceedings of the International Conference on Asian Digital Libraries , 2004
"... Abstract. This paper reports our research in the Web page filtering process in specialized search engine development. We propose a machine-learning-based approach that combines Web content analysis and Web structure analysis. Instead of a bag of words, each Web page is represented by a set of conten ..."

of contentbased and link-based features, which can be used as the input for various machine learning algorithms. The proposed approach was implemented using both a feedforward/backpropagation neural network and a support vector machine. An evaluation study was conducted and showed that the proposed approaches

Authoritative Sources in a Hyperlinked Environment

by Jon M. Kleinberg - JOURNAL OF THE ACM , 1999
"... The network structure of a hyperlinked environment can be a rich source of information about the content of the environment, provided we have effective means for understanding it. We develop a set of algorithmic tools for extracting information from the link structures of such environments, and repo ..."

; these connections in turn motivate additional heuristics for link-based analysis.

Measurement and Analysis of Online Social Networks

by Alan Mislove, Massimiliano Marcon, Krishna P. Gummadi, Peter Druschel, Bobby Bhattacharjee - In Proceedings of the 5th ACM/USENIX Internet Measurement Conference (IMC’07 , 2007
"... Online social networking sites like Orkut, YouTube, and Flickr are among the most popular sites on the Internet. Users of these sites form a social network, which provides a powerful means of sharing, organizing, and finding content and contacts. The popularity of these sites provides an opportunity ..."

Relational Link-Based Ranking

Distortion invariant object recognition in the dynamic link architecture

by Martin Lades, Jan C. Vorbrüggen, Joachim Buhmann, Christoph v. d. Malsburg, Rolf P. Würtz, Wolfgang Konen - IEEE TRANSACTIONS ON COMPUTERS , 1993
"... We present an object recognition system based on the Dynamic Link Architecture, which is an extension to classical Artificial Neural Networks. The Dynamic Link Architecture ex-ploits correlations in the fine-scale temporal structure of cellular signals in order to group neurons dynamically into hig ..."

Consensus and cooperation in networked multi-agent systems

by Reza Olfati-Saber , J Alex Fax , Richard M Murray , Reza Olfati-Saber , J Alex Fax , Richard M Murray - Proceedings of the IEEE , 2007
"... Summary. This paper provides a theoretical framework for analysis of consensus algorithms for multi-agent networked systems with an emphasis on the role of directed information flow, robustness to changes in network topology due to link/node failures, time-delays, and performance guarantees. An ove ..."

Rho GTPases and the actin cytoskeleton

by Alan Hall - Science , 1998
"... The actin cytoskeleton mediates a variety of essential biological functions in all eukaryotic cells. In addition to providing a structural framework around which cell shape and polarity are defined, its dynamic properties provide the driving force for cells to move and to divide. Understanding the b ..."

their interaction with multiple target proteins, they ensure coordinated control of other cellular activities such as gene transcription and adhesion. The story begins back in the early 1990s with the analysis of Rho, then a newly described member of the Ras superfamily of small guanosine triphosphatases (GTPases

Loopy belief propagation for approximate inference: An empirical study. In:

by Kevin P Murphy , Yair Weiss , Michael I Jordan - Proceedings of Uncertainty in AI, , 1999
"... Abstract Recently, researchers have demonstrated that "loopy belief propagation" -the use of Pearl's polytree algorithm in a Bayesian network with loops -can perform well in the context of error-correcting codes. The most dramatic instance of this is the near Shannon-limit performanc ..."

nothing directly to do with coding or decoding will show that in some sense belief propagation "converges with high probability to a near-optimum value" of the desired belief on a class of loopy DAGs Progress in the analysis of loopy belief propagation has been made for the case of networks
